"MacLac" which combines the previous owner’s name and the word “lacquer”, is an adaptive reuse of a historic brick structure that had been occupied by a paint and lacquer factory since the mid-20th Century. This edifice was known as “Building D”. The adaptive reuse design Introduces abundant daylight through ridge skylights; provides architectural lighting to highlight historic brick walls and new perforated metal stairs; seismically upgrades steel trusses of the original building; integrates crucial earthquake resistance elements, and adds a structural diaphragm creating usable area.
